Description

Technical Field

[0001] This invention relates to the field of smart construction site safety management technology, specifically to a safety mutual vibration system for environments without communication signals. Background Technology

[0002] The simplest and most practical function of a safety helmet is to protect workers' lives; impact protection is currently its primary function. With technological advancements, the protective applications of safety helmets will expand to more work conditions. Currently, there is much focus on long-term monitoring and construction site safety management, but very little on responding to emergencies.

[0003] Safety management in construction sites largely employs methods such as safety inspections, behavioral recognition monitoring, VR-based construction site safety education, and various safety monitoring techniques, including facial recognition, helmet-wearing recognition, access control systems, equipment sensors and monitoring, video surveillance, and drone inspections. It also utilizes IoT terminals and artificial intelligence technologies to achieve intelligent and real-time construction site safety management. However, many smart helmets integrate too many functional modules, making the products overly complex and causing problems in production costs, maintenance costs, power consumption, and battery life. High-performance smart helmets are also technologically expensive, typically limiting their application scope.

[0004] Existing smart safety helmets rely too heavily on IoT and communication technologies, typically employing monitoring solutions such as cameras and sensors. When a hazard is detected, information is first sent to a central control platform, which then sends specific rescue information to the appropriate rescue personnel. The rescue personnel then proceed to the hazard location to provide assistance, which cannot be done promptly and effectively. Furthermore, IoT and AI technologies are susceptible to external interference. For example, operational errors caused by environmental factors during work, equipment malfunctions due to external corrosion or damage in sudden situations, delays in information collection, and poor information sharing can all lead to accidents or even escalate their impact, causing significant loss of life and property. Particularly serious is the fact that once an accident occurs at a construction site, there is a high probability of power outages and signal loss, preventing timely information transmission and feedback. In dark / bright light and high-noise construction environments, workers cannot receive danger signals through light sensors or voice prompts. Summary of the Invention

[0005] The purpose of this invention is to provide a safe mutual assistance vibration system for environments without base station signals or mobile phone signals, which can effectively realize mutual rescue in the absence of communication signals and maximize the safety of workers in such environments.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A safety mutual vibration system for environments without communication signals is built into a safety helmet, comprising a sensing module, a positioning module, a storage module, a linkage module, a triggering module, and a power supply module. The sensing module is used to sense external light intensity, humidity, pressure, or other environmental signals; the positioning module is used to locate the current position of the safety helmet; the storage module is used to store information about the personnel wearing the safety helmet; the linkage module is used to establish communication connections with several surrounding safety helmets; the triggering module is used to trigger the safety helmet to vibrate, emit sound and light, or trigger other alarms; and the power supply module is electrically connected to the sensing module, positioning module, storage module, linkage module, and triggering module. The sensing module is communicatively connected to the triggering module, and the triggering module is communicatively connected to the linkage module.

[0007] Furthermore, the light intensity, humidity, pressure, or other environmental signals sensed by the sensing module are compared with the safety thresholds for light intensity, humidity, pressure, or other environmental signals built into the storage module. When the sensed value exceeds the safety threshold, the trigger module and linkage module are activated.

[0008] Furthermore, it also includes a remote radio module, which is communicatively connected to the positioning module, the storage module, and the triggering module.

[0009] Furthermore, the linkage module sends and receives signals at intervals, and only signals that reach the signal strength threshold can communicate with each other, thereby realizing signal interconnection and alarm triggering among several safety helmets in the vicinity.

[0010] Furthermore, this system is fixed to the inner top of the safety helmet via a mesh bag inside the helmet, and the mesh bag is connected to the helmet strap.

[0011] Compared with the prior art, the present invention has the following advantages: This invention discloses a safety mutual assistance vibration system for environments without communication signals. It solves the technical problems of existing rescue systems, such as high cost, inability to cope with dark / high-light and high-noise construction environments, and inability to effectively achieve mutual assistance and rescue in environments without communication signals. It enables the installation of different types of specific sensors according to different scenarios (mines, tunnels, valleys, etc.) and different needs (chemical, petroleum, coal mines, etc.), effectively responding to emergencies and maximizing worker safety. Specifically, by adding an interconnection system and LoRa (Long Range Radio) to existing safety helmets, it enables nearby rescue in the absence of communication signals, avoiding the impact of power outages or signal loss on rescue information transmission in emergencies. Vibration modes alert construction workers, preventing them from being unable to receive signals in high-noise and high-light environments, providing more effective and efficient protection for construction worker safety. It is suitable for use as a rescue interconnection system in smart construction sites, or for further improvement of similar systems. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of the safety helmet structure of the present invention. Detailed Implementation

[0014] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figure 1 As shown, a safety mutual vibration system for environments without communication signals is built into a safety helmet, including a sensing module, a positioning module, a storage module, a linkage module, a triggering module, and a power supply module. The sensing module is used to sense external light intensity, humidity, pressure, or other environmental signals, which may include velocity, acceleration, sound, or temperature. The positioning module is used to locate the current position of the safety helmet. The storage module is used to store information about the personnel wearing the safety helmet. The linkage module is used to communicate with several surrounding safety helmets. The linkage module has the functions of signal transmission and reception, signal connection, and signal search. The linkage module sends signals to and receives signals at intervals, and only signals that reach a signal strength threshold can communicate with each other, thereby realizing signal interconnection and alarm triggering among several surrounding safety helmets. The triggering module is used to trigger the safety helmet to vibrate, emit sound and light, or trigger other alarms. The power supply module is electrically connected to the sensing module, positioning module, storage module, linkage module, and triggering module.

[0016] The sensing module is communicatively connected to the triggering module, and the triggering module is communicatively connected to the linkage module. The light intensity, humidity, pressure, or other environmental signals sensed by the sensing module are compared with the safety thresholds for the same signals built into the storage module. When the sensed value exceeds the safety threshold, the triggering module and the linkage module are activated.

[0017] The sensing module includes a light intensity sensor, a humidity sensor, a pressure sensor, a temperature sensor, a speed / accelerometer sensor, and a sound sensor. When the light intensity sensor's reading exceeds a preset safety threshold, it is considered a fire or a sudden signal connection hazard; when the humidity sensor's reading exceeds a preset safety threshold, it is considered a water leak or sudden water surge hazard; the pressure sensor detects the movement of surrounding objects and potential explosion hazards; the temperature sensor identifies the ambient temperature; the speed / accelerometer sensor detects vehicle or equipment movement hazards; and the sound sensor detects explosions and rock fracture hazards.

[0018] The triggering module can also broadcast emergency information including the location of the person, facilitating mutual assistance among nearby safety helmet users.

[0019] Furthermore, it also includes a remote radio module (LoRa module), which is communicatively connected to the positioning module, storage module, and trigger module respectively; in the absence of a signal, the trigger module connects to the remote radio module and transmits the helmet positioning information, the device's unique number, and safety information to the remote control center.

[0020] like Figure 2 As shown, the system is housed in a mounting box, which is connected and fixed to the inner top of the helmet via a mesh bag inside the helmet. The mesh bag is connected to the helmet strap. The mounting box is detachable for easy replacement or maintenance.

[0021] The trigger module uses a small motor built into the helmet to cause the helmet strap to vibrate, thus triggering an alarm. This structure can identify whether the helmet is separated from the mounting box, thereby determining the current usage status and enabling timely detection and repair of helmet problems.

[0022] The working principle of this invention is as follows: The storage module of the safety helmet presets the safety thresholds corresponding to each sensor in the sensing module. The signal sensing values ​​of light intensity, humidity, pressure, temperature, speed / acceleration, and sound received by the sensing module are compared with the safety thresholds. When the comparison result exceeds the safety threshold, it is considered that a dangerous situation has occurred to the person wearing the safety helmet. The triggering module triggers a vibration or audible and visual alarm, and at the same time triggers the linkage module to send a signal. According to the set signal strength threshold, a signal communication connection is formed with the linkage module of one or more surrounding safety helmets. The interconnected safety helmets also trigger vibration or audible and visual alarms. Preferably, the triggering module can also communicate with a remote radio module (LoRa module) to further transmit the danger information to an external control center.

[0023] Using the above methods, effective nearby rescue can be achieved through helmet vibration or sound and light alarms even in the absence of base station or mobile phone signals, without the need for a back-end control center to receive, judge, and then release rescue information, thus saving the rescue process.

[0024] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the concept of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
